Arranging data into an array is an extremely useful process that allows scientists to be able to study and manipulate the information. When working with data arrays, one of the most important pieces of equipment is a scanner. Essentially, the function of an array scanner is to extract data from the array and render that information into a form that a computer can read and display.
As indicated by the name, a microarray is simply an array that is very small. The small surface of a microarray is often a slide for a microscope. The array is populated when a scientist places numerous extremely tiny samples (DNA, for example) onto the slide. Once the samples are on the slide, it can be inserted into a microarray scanner for analysis. Microarrays and scanners have applications in many different industries, including genetics, biology, and pharmaceuticals.
1. Sensitivity
When choosing an array scanner, one of the most important features to consider is the sensitivity. The equipment must be sensitive enough to accurately detect and analyze the required samples. When the data in the microarray is sparse or difficult to detect, the sensitivity of the scanner can have a significant effect on the precision and accuracy of the results.
2. Ease of Use
Another key feature of a microarray scanner is the simplicity of use. A good scanner should have displays that are easy to read and controls that are clearly labeled. Some models have touchscreen technology. It is also important that the scanner is easy to connect to a power supply and external devices, such as a keyboard.
3. Resolution
Like the sensitivity, the resolution of a scanner is a vital feature. To be useful, a scanner must have a resolution that can display data and results in a way that matches the parameters of the experiment.
Microarray scanners are extremely useful pieces of modern technology that play a vital role in many applications. When choosing an array scanner, some key considerations are the resolution and sensitivity. A scanner should also be easy to operate.
